“I’m telling you, I will never give up. I always have hope there’s information out there that could crack my sister’s case and all the other missing persons and cold cases in Connecticut,” said Mary Engelbrecht.

The Tolland County Cold Case Squad was established in October 2014 to investigate the disappearances of Pockett, as well as 13-year-old Debra Spickler, and 13-year-old Lisa White. All three disappeared between 1968 and 1974.

Debra Spickler:Spickler, of Mystic, was staying with family in Vernon when she was last seen at Henry Park on July 24, 1968. She was last seen walking alone in the direction of the Henry Park swimming pool.

Janice Pockett:Pockett was 7 when she left her home on a bicycle on the afternoon of July 26, 1973 and was last seen riding in the area of Anthony Road and Rhodes Road in Tolland. Her bicycle was found on the dirt portion of Rhodes Road, but there was no sign of her.

Lisa White:White was 13 when she was last seen walking on Prospect Street in Rockville after visiting with a friend during the evening of November 1, 1974. She lived around two miles from Prospect.

The cases have not been solved and the website for the Tolland County Cold Case Squad says $50,000 rewards are being offered for information that leads to an arrest and conviction in the three cases.
